About the Spline Modification User Interface
To modify a spline, select the spline and click
, or double-click the spline in the Sketcher window, the
Spline tab opens.
Commands
Use the commands to specify interpolation or control points when changing x or y coordinates. In addition, you can perform the following functions:
• Click
Control Points to set the type of editing outside the
Spline editing tab. When you select this command, you cannot change the
Edit Type.
• Click
Interpolation Points to modify spline using interpolation points.
• Click
Control Points to modify spline using control points.
• Click
Display Tools to show the curvature analysis tools.
Tabs
• Point—Change the x and y coordinates for interpolation. Also, move points to an absolute value or relative to the current value.
• Fit—Remove redundant data by the following methods:
◦ Sparse—Remove within a deviation tolerance.
◦ Smooth—Remove by averaging.
• File—From the File tab you can:
◦ Associate spline points with a coordinate system
◦ Read point coordinates from a file
◦ Save point coordinates
◦ Display coordinate information
◦ Change the coordinate system to Cartesian or Polar.
Shortcut Menu
Right-click a point on the spline in the Sketcher window to access the shortcut commands:
• Add Point—Add a point.
• Delete Point—Delete a point (includes end points).
